Abstract: The invention provides an improved multi-port fiberoptic rotary joint capable of transmitting increased amount of information between a rotating member (2) and a fixed member (4) through increased number of light beams without increase in loss of light. 
     In the rotary joint of the invention, a trapezoid prism (11), a pair of cylindrical lenses or a slab lens is provided between a rotating member (2) and a fixed member (4), rotatable and coaxial with the rotating member. Pairs of optical fibers (1a,1b,1c,1d)(6a,6b,6c,6d) are respectively facing each other across the prism, a pair of the lenses or the lens. The rotary joint includes a mechanism for rotating the prism (20,21,24 and 25), a pair of the lenses or the lens at an angular velocity half that of the rotating member around its optical axis. 
     Pairs of rhomboid prisms (16a and 14a or 16d and 14d) having their outer ends on coaxial circles of different diameters on the rotating and stationary sides, respectively, or pairs of rhomboid prisms ((14a,16a) or (14b, 16b)) each having at least one interface are provided to deflect light beams from the region outside the aperture of a trapezoid prism (11) into the region within the aperture, on the rotating side, and vice versa on the stationary side. 
     A pair of cylindrical lenses (51,52) or a slab lens (71) used in the rotary joint is free from loss of light due to defects on the surface, such as scratches or spots.

Abstract: The circuit arrangement according to the invention is used for generating a predetermined number of output pulses between in each case two successive input pulses, the spacing of the input pulses being able to vary. The output pulses should have an approximately equal distribution but this cannot be maintained when the period of the input pulses changes. To achieve, above all, the total number of output pulses as quickly as possible when the input pulse period changes, the circuit has a first counting arrangement which supplies a measure of the duration of the period of the input pulses referred to a clock pulse, and this measure is used as input value for the next period for a further counter which periodically counts down the input value with the clock pulses. The carry pulses of the further counter essentially specify the output pulses. Their number is counted in each period with the aid of a third counter which ends the further generation after the predetermined number has been reached in the respective period and when the input pulse period is shortened, pulses of which not enough had been generated will be additionally inserted in the next period. As a result, the total number of the output pulses is matched as quickly as possible to the predetermined number even if at the expense of uniform distribution. …<IMAGE>…

Abstract: A disk storage apparatus in which data is stored and read from tracks on a storage disk (10) by means of a head (2). The head can be selectively positioned over any one of the tracks by a head actuator (4). Error detecting means (14) generate a position error signal indicating error in the position of the head relative to a selected track, and control means supply a position control signal to control the actuator in response to the position error signal. The control means include an integrator (28) to integrate the position error signal to compensate for steady error in the position of the head. The apparatus further includes a head speed detecting means (24) for detecting movement of the head by the actuator within a predetermined speed range and switching means (26) controlled by the speed detecting means to prevent integration of the position error signal except when the head is moving within the said speed range.

Abstract: 5 n7 An apparatus for facilitating communications between an analog device and a digital device comprising a transmit circuit for processing outgoing signals, a receive circuit for processing incoming signals, and a control circuit for controlling the transmit circuit and the receive circuit. The transmit circuit includes transmit attenuators for attenuating the outgoing signals as they pass through the transmit circuit, and an analog-to-digital conversion circuit for converting analog signals to digital signals. The receive circuit includes receive attenuators for attenuating the incoming signals as they pass through the receive circuit and a digital-to-analog conversion circuit for converting digital signals to analog signals. Each of the transmit attenuators and the receive attenuators is digitally adjustable by the control circuit. The control circuit receives sensed outgoing signals from the transmit circuit and sensed incoming signals from the receive circuit and effects a comparison of the sensed outgoing and incoming signals to determine whether the apparatus is transmitting or receiving. The control circuit digitally adjusts the transmit attenuators and the receive attenuators to increase signal attenuation in the receive circuit and reduce signal attenuation in the transmit circuit when the apparatus is transmitting, and to increase signal attenuation in the transmit circuit and decrease signal attenuation in the receive circuit when the apparatus is receiving.

Abstract: A clock buffer circuit (10) for a computer system, and a computer system incorporating the same, are disclosed. The clock buffer circuit includes a differential input buffer (14) for receiving the input clock signal, with its output coupled to the input of a phase locked loop (PLL) (20). The switching level of the differential input buffer is adjustable (18), either by adjusting the DC bias applied to the input clock signal, or by adjusting the reference signal, which changes the point in the cycle of the input clock signal at which the differential buffer switches. The PLL synchronizes its output to an edge of the output of the differential buffer, but maintains the same duty cycle (e.g., 50%). Accordingly, the clock buffer circuit may have its delay adjusted, by modifying a voltage divider, applying a variable voltage, or programmably via a digital-to-analog converter, to match the delays of other clock buffer circuits in the computer system, reducing the clock skew in the system. A sine wave may be used as the input clock signal, so that harmonic noise is reduced in the system.
